But Tyler says his good deed was quickly overshadowed when he went back inside to his job.

"I understood when I went back in there that I was probably going to get into some sort of trouble because Best Buy policy says we're not supposed to touch anybody,” he said.

One week later, Tyler says he was given the pink slip.

"My manager told me that corporate had decided to let me go because I used excessive force, and it was against Best Buy's policy to intervene,” Tyler said.

A Best Buy representative issued a statement in response that said it is against company policy to engage any potential criminals.

“Our policy is clear: employees are not to chase potential criminals outside of the store. Chasing an individual in the parking lot creates a safety risk that isn’t worth taking, regardless of how noble an employee’s intention is,” the statement read.

Tyler says he has no hard feelings toward his former employer. He’s just happy knowing he helped put the suspect behind bars.
